Shattercane and grain sorghum [Sorghum bicolor (L.) Moench] seeds were buried at three depths for various times. Few grain sorghum seeds were viable 4 months after burial regardless of burial depth. None were viable 8 months after burial.
Only a few shattercane seeds from compact panicles were viable 4 months after burial, but some remained viable 3 years, mostly at the deeper burial depths (30.5 to 38.0 cm). Light was not a major requirement for germination after seeds were retrieved from burial regardless of time buried.
Some shattercane seeds from open panicles germinated after retrieval from all three burial depths even after 3 years. In general, number of viable seeds increased as depth of burial increased regardless of time buried. Germination, light-dependent in many wild cane seeds from open panicles, increased in light dependence with length of burial.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
